I thought my image host was always up and did have enough bandwidth to support my images, most of my images are screenshots I took with a tool. Now apparently I've got a mail that I'm reaching the bandwidth limit for free users, which means that if I continue to use the tool like this I will simply get out of bandwidth and a lot of my answers will then just show broken images.

Other than that, I eventually have infrequently used a link that points to an external source.

It would be handy if I could port my images to imgur in order to prevent this problem.

How do I go about and do this in an automatized manner? Perhaps this can be interesting as a solution?

If there is no automation possible or if it is prohibited, how do I form a Data Exchange query to find images?
